ASTM D849-15(2019)e1
(Test Method)Standard Test Method for Copper Strip Corrosion by Industrial Aromatic Hydrocarbons
Standard Test Method for Copper Strip Corrosion by Industrial Aromatic Hydrocarbons
SIGNIFICANCE AND USE
5.1 This test method is suitable for setting specifications, for use as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials. It also gives an indication of the presence of certain corrosive substances which may corrode equipment, such as acidic compounds or sulfur compounds.
SCOPE
1.1 This test method covers the corrosiveness of industrial aromatic hydrocarbons to a copper strip.
Note 1: For a similar copper strip test applicable to other petroleum products, see Test Method D130 and Test Method D1838.
1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
